Data Visualization Software

The project team chose Electric Eye as the data visualization software for use in the IMDS because of its power and flexibility. The system can: load up to 8 points of one-minute data for a 12-month period, or 4,204,800 values. It offers point and click commands with zoom and screen capture. The calendar and time feature allow the user to select days from a calendar with several time-aggregation options (minute, five-minute, hourly, etc.). Additional features include: 

  • Scroll vs. Slide mode: View one or more time series in scroll or slide mode. In scroll mode, view one day at a time. In slide mode, view a day, a week, or other time period to form patterns and erroneous profiles and to track operation.
  • 3-D Plots: View carpet plots for data point vs. time of day vs. day, or create your own xyz plots. Motion function allows for individual rotation and review of data points.
  • Statistics: Use in 2-D or 3-D plots. Get slopes, efficiencies, kWh demand and costs.
  • Section: Look at planes in 3-D plots for easier understanding of daily profiles, operation, and trends. See how temperature, power demand, equipment startup, and seasonal variations affect operation.
  • Equations: Trend data to form special equations or matrix. Fit linear, quadratic, and hyperbolic functions to 2-D plots.

The software runs on a Linux platform. The Linux PC can be accessed remotely through standard remote access software; however, it also functions as a web server and runs a Java version of the program which can be accessed through any web browser.
